README
# blob - a 8-neighbour connected components labelling and contours extractor.
See [blob.h](blob.h) for a complete documentation.
## Reference ##
"A linear-time component-labeling algorithm using contour tracing technique"
by Fu Chang, Chun-Jen Chen, and Chi-Jen Lu.
## Example ##
The [test](test) directory contains the source code of a small program that generates an image of the label buffer as long as a JSON file and a GNUplot data file containing the set of extracted contours.
#### source
#### label
#### contours

## Build ##
A CMake configuration file is provided in order to build a static library and the associated documentation.
A typical usage of CMake may be:
```bash
mkdir build
cd build
cmake ..
cmake --build .
```
On a Linux system, the Makefile will generate a static library `libblob.a`.
`cmake --build . --target doc` will generate the documentation with [DoxyGen](http://www.stack.nl/~dimitri/doxygen/).
